Synopsis ========
Two vulnerabilities have been discovered in sudo, allowing local attackers to possibly gain escalated privileges.
Background ==========
sudo allows a system administrator to give users the ability to run commands as other users.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.8.3_p2 >= 1.8.3_p2 *>= 1.7.4_p5
Description ===========
Two vulnerabilities have been discovered in sudo:
* When the sudoers file is configured with a Runas group, sudo does not prompt for a password when changing to the new group (CVE-2011-0010). * A format string vulnerability exists in the "sudo_debug()" function (CVE-2012-0809).
Impact ======
A local attacker could possibly gain the ability to run arbitrary commands with the privileges of other users or groups, including root.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All sudo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.3_p2"
